VitalStar

VitalStar is a China-based biotechnology company focused on genetically modified, humanized, and disease-model rodents for biomedical research and preclinical evaluation. Founded in 2000, the company provides custom model generation, breeding and colony management, embryology and microbiology services, transplantation studies, and in vivo pharmacology support for small molecules, biologics, and cell and gene therapies. Its offerings include immunodeficient and humanized mouse strains such as NPG mice, tumor and metabolic disease models, and liver-humanized systems for hepatitis research and antiviral drug screening. Rather than advancing a proprietary therapeutic drug pipeline, VitalStar operates as a research-tools and services company supporting pharmaceutical, biotech, and academic customers.
